To all 'whom 'it may concern:

ABe 1t known that we, OTTO SOHNI and HENRY MEHL, citizens of the United States,

residents of Buffalo, in the county of Erie and State ofNew York, have made acertain new and useful Invention in Seal-Padlocks; and we declare the following to be a full, clear, and exact description of the same, such as will 'enable others skilled in the art to which it ap Jertains to make and use the in'- vention, re erence being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

- Figure 1 1s a central vertical section of our padlock. Fig. 2 is a side view of the saine. 3 is a sectional view 'similar to Flg. I with'the sealbroken and one branch of the hasp turned half around. Fig. 4 is a section of the padlock, taken on fthe, line 4-4 Fig. 1. Fig is a section on the line 5--5 Fig. 3. Fig.` 6 is a ldetail perspective View of lthe block and attached awls. v Fig.

' two 7 is a central vertical section o a modied .form of the invention. Fig. 8 is a similar view of a second modification-of the invention. Fi ..9 is a;detail sectional view-of the ,view of the block andspring in'such fourth modification.

The invention has relation to seal pad# locks, designed for sealing freight orbox cars, and which cannot he broken without Vthe use of a bolt cutter or similar tool of comparatively large or clumsycharacter and operating -with considerable noise.

Other objects and advantages will hereinafter appear. x .h lrn the accompanying drawings, illustrating the invention, the etter a, indicates the incasement or body of the padlock, having parallel longltudinal cylindrical r forations b, b, one at each side, and provided at one end with a recess c, between said perforations and communicating at each side therewith at c', c. a block d, which is secured to the body a, by two rivets e, c, said block carrying two pivoted pawls f, f,having a light coil-spring g, engaging studs j", f. of the pawls and holding the same normally thrust outward In the recessl c, is fitted away from each other into the perforations 7h, is a staple-forni hasp or shackle, havin two parallel legs L, k', of equal length whi engage the perforations b, b, and are provided each with a series of sharp ratchet teeth i, having shoulders z, at right angles to the axis of the leg, and inclined sides i2, three such teeth being shown. This shackle is usually formed of a cylinder bar of malleable iron bent centrally and having the teeth thereof forged -or filed therein. i

In the use of the device, the lh asp -or shackle has the le's thereof pushed within the perforations of the bod ya, one leg being previously engaged with the staple 7, of the car door over which the 'usual plvoted slotted hasp j', fits, such legs as they pass -within the perforations b, b, having almed teeth of the op osite legs engaged by the end faces f2, of t e pawls f, f, which are rst pushed back by said legs without such perforations and then spring within the same again when the notches above the ratchetteeth. and vbetween the same come into aline ment with the pawlsf- In order to relieve the pivot-pins fx, f,of the pawls of strain when the shackle is pulled or pried u ward with the object of breakin thesea said pawls have transverse slots fY, of slightly lar er diameter than and loosely engaging sucI1-pivot-pins. the pawls being `provided with lateral shoulders` f, f3, which are adapted to take a bearingvagainst the lower face of the block (Z. e

Should any of the ratchet teeth i, become worn or dulled, other teeth thereof maybe employed for engagement with -the pawls, the object being to obtain quick sharp action of the pawls in engaging the teeth.

When the legs of the staple-form hasp or shackle are pushed through the perforations b, b, the perforated ends thereof, shown at b', b', may be connected with the usual wire and lead sealfwhereby it is made apparent if the device has been tampered with.

When it is desired to break the seal, a bolt cutter or other suitable tool is-employed to cut through one branch of the st-a le-form shackle h. when upon turning a leg of the shackle within its cylindrical seat, the tooth i, thereof will be turned out of engagement with pawl f, engaging the same, such pawl being at the same time pressedinward within the seat in the block d,- when thesepl :Hated legs of the shackle may be pulled out l A coiled spring 1n, .isseated in." the aperture, opposite outturned end portions l', l', thereof being;l located in the vnotches .or recesses c,"lc2, and noriiiall projecting at' their extremities?, l, beyon 'the ends ot' the block into theperforatons b, b. Thus when thelegs'ot the staple'fshackle are' passed within the perforations, the 4outturned end portions Z.':, Z, of th`e .coil spring will' be engaged-,with alined teeth. thereof tol se- 2- 5 curelyliold thestaple and 'scalthe padlock -and cai- 'doon In this form of the device fwhen it desiredto break the seal, the bpdy of-the padlock is driven by suitable iin le-` inents downward from`` the staple sh'ac (le,

which is secured to the 'car by means of an' eye Z2, :it 'its upperl end having chain con` f nection ZTfwith the .car when` the endpor- -v tions l', l', of the'springfwill bear against the upper walls 1.13, k", of th; ',notehes le', k2,

In Fig; H of the drawings isshown :i furthor inoivlifieation of the -inveiit ion where- `'p50 in the 'block (l, is' proyided with a transverse- 'cylindrical aperturev 19,; in "which is', seated. a c oil spring n','tl`ie'.roiittiiined end portions n, ofwhich lie below the block 1Z, a nd closcly adjacentthereto; ,The operation' of, the' ina-,reution in this iiiodiiedforin isfsi'inilaato the 'operation thereof-intheffirst modifical tion e'reiiibefoie described.'y A ii Figgfg) of lhe drawings a' third 'modification ofthe invention VisA shown, wherein the block "1l, isprovidedmtlila transverse open' ingI o ,-w lierein. is' seated .the eylindriciilly bent central portion of a fiat plate spring;` o', having outtui'ned end portions o2, lying' below the block d, and' closely adjacent there- ."465 in, and the extremities ofwhich `project, henr-l mally beyond the ends of the block within the perforations 5,21, intoYengager'nent'With alined teeth of 'the stapleshacklelega, Th operation of the invention .in "this ,fo1"m"" thereof is similar to the operation thereof qi0. in the other modifications referred to. f

A fo'urth vmodification is s hWn' in Fig. 11 of the drawings, wherein a4 postlp, is seated removably in the padlock body [at p', sii-id post. carrying at its upper end in a slot p 715- thereof, a 4coil spi-in g, the oiitturned en portions g', of whic are designed for enrrangement with the teeth of the .sta le shackle .asheiore described.
